It was not formatted as pre-formatted text so it failed when I tried to format it but I just edited your post to format is properly and now you can paste that same text into [Best JSON Viewer and JSON Beautifier Online](https://codebeautify.org/jsonviewer) to see the data structure:

When I click on the CZT key, it shows the path to that value at the top (object → 1 → CZT). So in Thunkable, you would set the property “[1].CZT” or set the property “CZT” of the first list item in the object.

I haven’t set JSON properties before so if it were me, I’d make sure I can **get** that key value (“CZT”) before attempting to set it to something else.

You can find out more by watching my tutorial video here: [API JSON Tutorial (Video)](https://community.thunkable.com/t/api-json-tutorial-video/1140575).
